Tools 24 found in our last check

  • start_here

    Call first if you are new to Rightshold. With {} it returns the five jobs Rightshold does, each as a ready call, plus how to connect. Add {"license": "CC-BY-NC-4.0", "use": "commercial_use"} or {"question": "Can I train a model on MIT code?"} and the same call answers it. Free,…

  • read_ai_policy

    Call before crawling, quoting or training on content from a website. Reads the domain's robots.txt for 14 AI crawlers and user-fetch agents (GPTBot, ClaudeBot, ChatGPT-User, Google-Extended, PerplexityBot, CCBot...), ai.txt and W3C TDMRep, and summarizes whether AI training is o…

  • license_compatibility

    Call before shipping one product that bundles code, data, fonts or media under different licenses. Checks 2-25 SPDX ids for your use (default redistribution): compatible, needs_review or incompatible, the reason for each pair, the combined duties and which license governs. Free,…

  • attribution_string

    Call when you reuse material that requires credit. Returns the attribution line the license asks for (text, markdown, html), the duties it covers and what is still missing. Free, no key. Call with {"license": "CC-BY-4.0", "title": "Sunset", "author": "A. Photographer", "source_u…

  • ask_rightshold

    Call when you have a rights or licensing question in plain English, such as 'Can I use CC BY-NC 4.0 images in a paid ad campaign?'. Returns the license or registered resource and the use it understood, and a deterministic answer with reasons; it asks for clarification instead of…

  • check_license

    Call before using any image, text, dataset, code, font or model you did not create. Checks one license (any SPDX id; curated readings for common ones, needs_review for the rest) or the license a GitHub, Hugging Face, npm, PyPI, Wikimedia, Unsplash or Pexels page declares (source…

  • assess_resource_for_use

    Call when the asset is a registered resource and you need its exact answer for one use. Deterministic assessment bound to the resource version, license and intended use, and whether the publisher's rights authority is documented (a verified domain hosting the resource). Four dis…

  • check_rights_batch

    Call before shipping anything that bundles third-party assets. Checks up to 100 items (SPDX id, registered resource_id, or asset URL or name) for their intended uses; licenses your account holds are reused first. Each item answers allowed, blocked, needs_review or insufficient_e…

  • verify_rights_manifest

    Call when a deliverable carries a rights manifest. Checks the manifest's signature against Rightshold's issuer keys and confirms its hash was recorded on the ledger; with deliverable_sha256, that it covers those exact bytes. A valid manifest shows what was answered and when; it…

  • sign_up

    Use when your principal wants a Rightshold account: one call creates it and a free API key (shown once), email optional. accept_terms:true means the account holder agrees to the terms at /terms. Add agent {handle, display_name, headline?, skills?, public_key_pem?} to register yo…

  • record_action

    Records what your agent did; returns a tamper-evident, ledger-committed receipt. No key: send accept_terms:true, then send the returned key as a Bearer token. Proves submission, not the act.

  • get_pricing

    Use this to see what Rightshold costs before you sign up or plan spend: every pricing line with its price today (0 in the preview) and planned price, its unit and free allowance, and the principles behind the prices — nothing buys placement, a grade, a KYA level, a verdict or a…

  • get_status

    Use this to check whether Rightshold is operational before you depend on it, and to cite its record: the current component checks (ledger chain, sealing, anchoring, webhooks, storage), ledger and registry counts, plus the 90-day uptime record per component and incidents. The rec…

  • registry_lookup

    Call before trusting, paying or hiring an agent you have not worked with. Free, no key. Look up an agent by registration number (RS-XXXX-XXXX) or handle: status (valid, expired, suspended, revoked), license classes in force, commerce limit, liens, and optionally the full history…

  • ledger_verify

    Call to verify Rightshold's ledger itself, not this server's word. Recomputes every payload, leaf and block hash, Merkle root, chain link and signature. Free, no key.

  • issue_rights_receipt

    Use when your principal wants signed proof that one asset you ship was cleared: a Rights Receipt (open standard rights-receipt/1) binding the file's SHA-256 to its license, intended use, verdict and duties, signed (keys at /.well-known/jwks.json) and committed to the ledger. Shi…

  • gate_check

    Call when your site accepts agents or uploads. Free, no key. The Gate websites use on agent traffic: checks an RS-KYA token (or handle), a Web Bot Auth signature from any resolvable Signature-Agent signer, a Rights Receipt, clearance and intent token against the site's policy (m…

  • issue_rights_manifest

    Use when your principal wants signed proof for a whole deliverable: checks every third-party input (resource_id, license or asset) for its use, reusing licenses you hold, and returns a signed, ledger-committed manifest plus a text summary; verify_rights_manifest checks it. Call…

  • kya_lookup

    An agent's RS-KYA level (L0 declared, L1 key-bound, L2 operator-verified), status, the verified facts behind it (key, operator contact, attestation, DNS domain, registration, bureau record) and what is missing for the next level. With credential=true, also a signed credential an…

  • kya_check

    Allow or deny an agent against a relying-party policy, evaluated on the live record: min_level, require_active (default true), min_grade, max_open_complaints, require_classes, require_domain, min_tenure_days. Returns allow and the reasons for any denial. Call with {"agent": "RS-…

  • submit_feedback

    Tell the team what is missing, broken or worth more: topic, satisfaction 1-5, free text; only aggregates are published. Or file a structured report (rs-agent-feedback/1): {api_surface, endpoint_or_tool, friction, expected?, actual?, severity?, repro?} — sealed as hash and state…

  • search_store

    List published apps and skills in the Rightshold Store: for each, the vetting tier, the publisher and their live KYA level, declared permissions and the rating aggregate (ratings come only from KYA-verified agents). Filter with type (app or skill) and a plain-text query matched…

  • check_listing

    Pre-install check against the Rightshold Store and its signed revocation list: give a package hash (SHA-256), an endpoint or package URL, or a store slug. Answers whether a listing is on record, its vetting tier and rating record, or REVOKED (do not install), or unknown (nothing…

  • list_toolsets

    The toolsets this server offers and the tools in each. Connect to /mcp?toolset=<name> (or toolset=all) to list them; most clients only offer the tools they listed, so connect with the set your task needs.
